Definitions
- This invention relates to a power transfer arrangement for a work machine and more particularly to a power transfer arrangement having a prime mover oriented at a predetermined angle relative to a longitudinal axis of the work machine and a prime mover mounted transmission oriented at a predetermined angle relative to an elevational plane of the longitudinal axis and extending beneath a frame of the work machine.
- the amount of space available to access components of the engine is a function of the width of the machine, determined by the distance between sides of opposite wheel pairs, and the distance between the boom, and in some cases a centrally elongated frame portion, and one of the wheel sides. It is particularly important to keep the engine (including the engine compartment when provided) within the width of the machine in order to maximize stability and maneuverability. In doing so, the distance between the boom and/or central frame and the engine is extremely tight making access to engine components, such as, a turbocharger, alternator, oil and/or gas filter located therebetween difficult. Given the various prior power transfer arrangements, including, transmission, transfer gear case, differentials and the like available, engine repositioning is not possible due to interference with the frame or boom.
- a transfer gear case which has a multitude of gears, bearings and associated parts.
- Such transfer gear cases extend from a location substantially in line with the output shaft of the transmission to a location substantially transversely midway between the pairs of spaced apart opposite wheels.
- Several drive shafts are provided to connect the transmission to the transfer gear case and the transfer gear case to each of the front and rear differentials associated with each pair of wheels of the machine.
- the present invention is directed to overcoming one or more of the problems as set forth above.
- a transfer arrangement for transmitting rotary power from a prime mover to a ground engaging member of a work machine has a frame with a pair of spaced longitudinally extending and elevationally oriented side members, and first and second longitudinally spaced end portions.
- a longitudinal axis extends longitudinally relative to the longitudinal extension of the machine frame.
- a prime mover having a longitudinal centerline and an end is connected to the machine frame.
- the prime mover is located to a first side of the machine frame and the longitudinal centerline of the prime mover is located at a predetermined angle relative to the longitudinal axis.
- a transmission has an input gear and an output gear.
- the housing is connected to the end of the prime mover and the input gear is adapted to transfer rotary power from the prime mover to the output gear.
- the transmission is at a predetermined angle relative to the prime mover and extends to a location at which the output gear is elevationally beneath the machine frame.
- a first differential is connected to the first end portion of the machine frame and is located beneath the first end portion of the machine frame.
- the second differential is connected to the second end portion of the machine frame and is located beneath the second end portion of the machine frame.
- a first drive shaft is located between and connected to the first and second differentials.
- the first drive shaft has a longitudinal axis which extends substantially parallel to the longitudinal axis of the machine frame.
- the first drive shaft transfers rotary power between the first and second differentials.
- a second drive shaft has a longitudinal axis and is connected between the output gear of the transmission and the second differential.
- the second drive shaft is adapted to transfer rotary power between the output gear and the second differential.
- the second drive shaft longitudinal axis is at a first predetermined angle relative to the longitudinal centerline of the prime mover and at a second predetermined angle relative to the longitudinal axis of the vehicle frame.
- the angling of the prime mover relative to the longitudinal axis provides additional clearance space between the frame and the prime mover and the angling of the transmission relative to an elevational plane of the longitudinal axis enables substantial lowering of the prime mover and improved visibility from the operator's station mounted on the frame opposite the prime mover.
- Angling of the transmission enables the transmission to be tucked beneath the frame so that the longitudinal axis of the first and second drive shafts are substantially parallel to a transverse plane of the longitudinal axis which is oriented transverse relative to the elongate frame.

- FIG. 2 is a diagrammatic side elevational view of FIG. 1 taken along lines 2--2 of FIG. 1;
- FIG. 3 is a diagrammatic front elevational view taken along lines 3--3 of FIG. 2;
- FIG. 4 is an enlarged diagrammatic top plan view of FIG. 1 with portions broken away and removed to show the power transfer arrangement in greater detail;
- FIG. 5 is an enlarged diagrammatic front elevational view of FIG. 3, taken along lines 5--5, with portions removed and broken away to show the power transfer arrangement in greater detail.
- a work machine 10 in particular a telescopic handler, is partially shown.
- the work machine has a frame 12, first and second drive axle assemblies 14,16, and a boom 18.
- the frame has an elongated configuration defined by first and second substantially parallel spaced apart elevationally oriented side members 20,22 and first and second spaced apart end portions 24,26.
- loaders, non-telescopic handlers, combination loader handlers and the like are considered equivalents and within the scope of this invention.
- the first and second drive axle assemblies 14,16 each have a pair of spaced apart rotatable ground engaging members 28, for example, wheel assemblies, and an axle housing 30.
- the first and second drive axle assemblies 14,16 have respective first and second differentials 32,33 disposed within the axle housing 30 at a location between the ground engaging members 28.
- the first and second differentials 32,33 include a gearing arrangement, for example, planetary gearing arrangement of a conventional well known design.
- the ground engaging members 28 of each pair are rotatably connected to the axle housings 30 in a conventional manner, and rotate in response to rotation of an axle shaft (not shown) connected thereto.
- the axle shafts are connected to the differentials 32,33 and are responsive to rotation the differentials 32,33 in a conventional and well known manner.
- the first and second differentials 32,33 each have a rotatable input shaft 66 for purposes of driving the ground engaging members 28.
- the first and second axle assemblies 14,16 are connected at spaced apart locations to and beneath the first and second end portions 24,26, respectively, of the frame 12 and extend transverse relative to the a longitudinal extension of the frame 12.
- the differentials 32,33 are located transversely centrally beneath and connected to the frame 12.
- the ground engaging members 28 are substantially equally spaced from a longitudinal axis 46 extending longitudinally relative to the frame 12.
- the boom 18 has first and second spaced end portions 34,36.
- the first end portion 34 is pivotally connected to the first end portion 24 of the frame 12 and the second end portion 36 extends past the second end portion 26 of the frame 12.
- the boom 18 may have a telescopic portion (not shown) which is slidably extensibly movable in a conventional well known manner.
- the boom 18 has top and bottom sides 38,40 and is pivotally movable about the pivotal connection between first and second pivotally spaced positions.
- the boom 12 is nested between and spaced from the first and second side members 20,22 at the first position (FIG. 2) and spaced from being nested between the first and second side members 20,22 at the second position. Movement between the first and second positions is achieved by way of hydraulic jacks (not shown) in a conventional manner.
- the work machine 10 has a transfer arrangement 41 for transferring rotary power from a prime mover 42, for example, an engine, to the ground engaging members 28 of the work machine 10.
- the prime mover is substantially upright and located to a first side 44 of the frame 12 and to the longitudinal axis 46 extending longitudinally relative to the longitudinal extension of the frame 12.
- the prime mover 42 has a longitudinal centerline 48 and the prime mover 42 is connected to the frame 12.
- the longitudinal centerline 48 is at a predetermined angle "a" of between 4 and 12 degrees relative to the longitudinal axis 46 and preferably a predetermined angle "a" of 8 degrees.
- the angle "a" of the prime mover 42 is significant in providing access to the prime mover 42 between the centrally located frame 12 and the prime mover 42. Too great an angle “a” places the prime mover 42 outside the envelope of the machine 10 defined by the ground engaging members 28. As will be seen during further discussion, this angle "a” is also significant in minimizing drive shaft angles and thereby promoting extended life of the associated componentry.
- the power transfer arrangement 41 includes a transmission 50.
- the transmission 50 has a housing 52, and at least an input gear 54, and an output gear 56.
- the housing is connected to an end 58 of the prime mover 42 and rigid relative thereto.
- the transmission may be connected to a torque converter 59 of conventional and well known design.
- the input gear 54 is rotatable in response to rotation of a rotary member, such as a crank shaft (not shown), of the prime mover 42 in a conventional manner and transfers rotary motion to the output gear 56 in a conventional manner.
- the transmission 50 is tilted at a predetermined angle "b" relative to an elevationally oriented plane 60 of the longitudinal axis 46.
- the transmission is also at an angle to the substantially upright prime mover 42 and the longitudinal centerline of the prime mover is substantially parallel to the transverse plane 64.
- the prime mover 42 may be angled slightly, 10 degrees or so, relative to the vertical.
- the elevational plane 60 is preferably vertical and the longitudinal axis 46 lies in the plane 60.
- the angle "b" is between an angle of between 30 and 75 degrees and preferably 60 degrees.
- the transmission 50 an particularly the housing 50 thereof, extends to a location beneath the frame 12 so that a center axis 62 of the output gear 56 lies in a transversely oriented plane 64 transverse relative to the frame 12.
- the first and second drive axle assemblies 14,16, the spaced apart input shafts 66 and the longitudinal axis 46 axially lie in the plane 64.
- the longitudinal axis 46 passes through a center of rotation of the input shafts 66.
- a first drive shaft 68 has a longitudinal axis 70 and is located between and connected to the first and second differentials 32,33. In particular, the first drive shaft 68 is connected to rotate the input shafts 66 of the first and second differentials 32,33.
- the first drive shaft 68 is substantially parallel to the transverse plane 64. It is preferred that the longitudinal axis 70 lies substantially in the transverse plane 64. It is preferred that the first drive shaft 68 is at a slight angle to the transverse plane 64 so as to move slightly for lubrication purposes and extended life.
- a second drive shaft 72 has a longitudinal axis 74 and is connected between the output gear 56 of the transmission 50 and the second differential 33.
- the second drive shaft 72 transfers rotary power and motion between the output gear 56 and the second differential 33.
- the second drive shaft 72 transfers rotary motion from the output gear 56 to the input shaft 66 of the second differential 33.
- the longitudinal axis 74 of the second drive shaft 72 is at a first predetermined angle "c" relative to the longitudinal centerline 48 of the prime mover 42 and at a second predetermined angle "d" relative to the longitudinal axis 46 of the machine 10. It is desirable that the first predetermined angle "c" is between 3 and 5 degrees and the second angle "d” is between 3 and 5 degrees.
- first and second angles "c" and “d” are equal in magnitude, 4 degrees, so that the velocity at opposite ends of the second drive shaft is constant.
- the longitudinal axis 74 is substantially parallel to the transverse plane 64 and preferably lies in the transverse plane 64. In the preferred embodiment of the invention, the longitudinal axis 46 and the longitudinal axis 70 of the first drive shaft 68 are substantially coincident.
- a transfer gear case 78 is connected to the axle housing 30 associated with the second differential 33 and located beneath the frame 12.
- the transfer gear case 78 has a housing 80 and first and second transfer members, hereinafter referred to as first and second transfer gears 82,84, connected to the housing and rotatable relative to the housing 80.
- the housing 80 is mounted on the second drive axle assembly 16 adjacent the second differential 33 and fixed from movement relative to the second differential 33. This mounting may be by way of a flange and threaded fasteners (not shown) or any other suitable known mounting.
- the housing 80 of the transfer gear case 78 may be an integral part of the axle housing 30 rather than a separate unit.
- the transfer gear case 78 is disposed about the input shaft 66 of the second differential 33.
- the first transfer gear 82 is connected to the second drive shaft 72 and the second transfer gear is connected to the input shaft 66 of the second differential 33.
- the first and second transfer gears 82,84 are each rotatable about an axis of rotation lying in the transverse plane 64.
- the transfer gears 82,84 may be replaced by a suitable substitute, such as, a belt or chain drive arrangement having pulleys and cogs, respectively, without departing from the spirit of the invention.
- the first drive shaft 68 is connected to and between the second transfer gear 84 of the transfer gear case 78 and the rotary input shaft 66 of the first differential.
- a universal joint 76 or other suitable joint type, is provided at the connection of the second drive shaft 72 to the output gear 56 of the transmission 50 and at the connection of the second drive shaft 72 to the first transfer gear 82.
- a universal joint 86 or other suitable joint type, is provided at the connection of the first drive shaft 68 to the input shaft 66 of the first differential 32 and at the connection of the first drive shaft 68 to the second differential 33.
- the universal joint 86 at the connection to the second differential 33, is connected to the second transfer gear 84. It should be recognized that this connection may be to the input shaft 66 of the second differential 33 without departing from the spirit of the invention.
- An operator's station 88 is connected to the machine frame 12.
- the operator's station 88 is located to a second side 90 of the frame 12 opposite the first side 44 at which the prime mover 42 is located and to the second side 90 of the longitudinal axis 46.
- the operator's station 88 has a window opening 92 on a side facing the prime mover 42.
- the line of sight 94, of a typical sized vehicle operator, through the window opening 92 is substantially improved by the lowering of the prime mover 42 and the surrounding enclosure.
- the power transfer arrangement 41 transfers rotary power from the prime mover 42 to the transmission 50.
- the transmission 50 transfers rotary power to the transfer gear case 78 mounted on the second drive axle assembly 16 beneath the frame 12 by way of the second drive shaft 72.
- the first drive shaft 14 transfers rotary power between the transfer gear case 78 and the first differential 32.
- the first and second differentials 32,33 transfer rotary motion of the first and second drive shafts 68,72 by way of the axle shafts to the ground engaging members 28.
- the transmission being at the predetermined angle "b" relative to the elevational plane 60 enables the transmission 50 to be partially tucked beneath the frame 12 so that the output from gear 56 is beneath the frame 12 and in as close proximity as possible to the first drive shaft 68 in order to minimize the angles "c" and "d” of the second drive shaft 72 and thereby extend component life.
- This also allows for the transfer gear case 78 to be relatively smaller in size than conventional transfer gear cases, to be mounted on the second differential 33 in a simple manner, and to have fewer components than existing transfer gear cases.
- Having a portion of the transmission 50 beneath the frame 12 also allows the prime mover 42 to be placed at angle "a" relative to the longitudinal axis 46 which increases the amount of space between the prime mover 42 and the frame 12 and improved access to that area of the prime mover 42.
- first and second drive shafts 68,72 lie substantially in the same transverse plane 64 extreme compounded drive shaft angles are eliminated. Having the first and second axle assemblies 14,16 in substantially the same plane 64 further simplifies the design and promotes extended life and serviceability.
- the power transfer arrangement 41 therefore, improves the efficiency of operation of the machine 10 by improving the visibility in the direction of the prime mover for the operator.
- the lowering of the prime mover 42 and moving it as close to the longitudinal axis 46 of the machine 10 as practicable results in a lower of center of gravity of the machine 10 and better machine stability.
